AmazonFeed is all the same features, no restrictions and no annoying options page garbage. Still works with WP 3.5 and Multipress.
There use to be a "Better" version of this too. But, I can't find it anymore. It had even more options for the layout.
If anyone knows where to find it please let me know here.
